Hi @blessingogah
I got an idea of inflation in Nigeria after reading your business post, your vintage shirt would be worth around 800 rupees according to our price {Naira 100 = 10.37 rupees} today's rate. If the fabric of this shirt is known then it can be compard with India Coast. Similarly, in our country, men's jeans are available for about 10,000 Naira.
If you want, I can provide to you.
Thanks .
